RELATIONSHIP BETWEEN POLYETHYLENE WEAR AND OSTEOLYSIS IN HIPS WITHA SECOND-GENERATION POROUS-COATED CEMENTLESS CUP AFTER SEVEN YEARS OF FOLLOW-UP

Abstract
Background:The development of osteolysis, a commonly reported complication after total hip arthroplasty without cement, is perceived to be related to the amount of polyethylene particles generated from the bearing surfaces. Although the literature has suggested that the prevalence of osteolysis incr
